Appendix 3-IV Use of the observation method according to Eurocode 7 
Appendix 3-V Application of numerical models for geotechnical verifications. 
Other codes of practice may be applied according to the rules pertaining to deviations and 
amendments set down in chapter A3. 
Where required, transitional arrangements shall be agreed with the BSH on a case-by-case 
basis. 
3.3.1.2 Codes of practice for loads 
The national DIN standards and codes of practice do not cover, resp. do not completely cover 
all loads to which offshore structures are subjected. As a result, additional codes of practice 
shall be referred to accordingly. With respect to loads, reference is herewith made to the fol 
lowing standards and guidelines which can be used by the architect as a basis for determining 
the loads on the foundation elements: 
DIN EN 61400-3 
DIN 1055-4 
DIN EN 1991-1-4 
API RP 2A-WSD
